  • Abstract
    By using the differential operator technique and the effective field theory scheme we study the tricritical behavior of Heisenberg classical model of spin- in a random field. The phase diagram in the T–h plane on a square and simple cubic lattice for a cluster with two spins is obtained when the random field is bimodal distributed.
